Silverstripe 4 error log

问题

How can I log errors to file log in SilverStripe 4? I mean all errors causing 'Internal server error' info from SS

In SilverStripe it was :

SS_Log::add_writer(new SS_LogFileWriter('/var/log/silverstripe/errors.log'), SS_Log::ERR);

Documentation says that I need to do something like:

SilverStripe\Core\Injector\Injector:
  Psr\Log\LoggerInterface: 
    calls:
      LogFileHandler: [ pushHandler, [ %$LogFileHandler ] ]
  LogFileHandler:
    class: Monolog\Handler\StreamHandler
    constructor:
      - "../silverstripe.log"
      - "info"

I try this but cannot get this to work :(

回答1:

Try to add to your .env file (https://docs.silverstripe.org/en/4/getting_started/environment_management/) such string:

SS_ERROR_LOG = "silverstripe.log"

回答2:

To create a custom log try: use Monolog\Handler\StreamHandler; use Monolog\Logger; Then later: $logger = new Logger("my_name"); $logger->pushHandler(new StreamHandler('./silverstripe-custom.log', Logger::INFO)); $logger->info('hi there'); You should find silverstripe-custom.log in the project root.
